Is this Blossom End Rot?

ourhappyhome(7B)June 23, 2009

Is this blossom end rot? I have 9 plants and only the Romas are affected. The holes in the bottom seem a little too perfect. In the past when I've had BER, it was more of a dry, patchy spot and the tomatoes didn't rot like this. This is my first time trying Romas. Thanks for your help.
